Abstract

La présente invention concerne un dispositif d'affichage d'informations photographiques. Ce dispositif comprend une source d'informations photographiques 1, un moyen de porte 2, et un moyen d'affichage d'informations photographiques 3. Le moyen de porte 2 est lui-même commandé par un générateur d'impulsions 5 relié à un dispositif de détection de conditions anormales 4. Ces conditions anormales peuvent par exemple résulter d'une luminosité trop faible ou trop forte ou d'une chute de tension de batterie. Application aux appareils photographiques automatiques.
